HAMMOCK-SUPPORT.

SPECIFICATION fbrming part oi" Letters Patent No. 691,070, dated January 14, 1902. Application filed August 18, 1898. Serial No. 688,871. KNo model.)

To all whom it ntcty concern:

Be it known that I, ISAAC E. PALMER. a citizen of the United States, and a resident of Middletowu, in the county of Middlesex and in which- Figure l is a view in side elevation of the backbone and upper portions'of the supporting-legs, showing the backbone in its contracted closed adjustment. Fig. 2 is a similarviewshowingthebackboneextended. Fig. 3 is an end view, and Fig. 4 is a transverse section along the line 4 10f Fig. 1 on an enlarged scale.

The legs (denoted byA) may be of any wellknown or approved form and may be attached to the ridge-pole or backbone, so as to fold in a 'manner quite similar to that shown, described, and claimed in my pending application, Serial No. 679,179, filed on April 29, 1898. Their specific structure forms no part of my presentinvention.

The ridge-pole or backbone is made in the present instance in three sections, the central section being denoted by B and the end sections by B B The end sections 13 B are preferably each formed of separate strips, (denoted by b 19",) spread apart at the end where the leg is attached and brought together at the opposite end, where they are clamped to the central section B.

A clamping device for holding the parts I) b of the end section snugly together and clamping the end section as a whole snugly to the central section B in the desired extended adjustment is constructed as follows: A pair of cheek-pieces (denoted by O O) arefitted to embrace the opposite sides of the section B and the opposite sides of the end section B or B and at their lower ends are brought toward one another, as shown at c c, to partially embrace the under side of the end section. The parts I) b are fixed in positionbetween the lower ends of the cheek-pieces C C by means of bolts 0 0 which extend through the cheek-pieces and through the parts Z; Z), respectively. In the upper ends of the cheekpieces 0 0 there is eccentrically pivoted a cam D, provided with an operating-handle d. On the cylindrical portion of the cam D, intermediate of the cheek-pieces O C, a shoe or shoes-in the present instance shoes EE'- are loosely mounted, the lower faces e e of the said shoes being extended lengthwise of the ridge-pole B, so as to secure an extended and firm grip upon the ridge-pole to hold it in position. E with respect to the upper face of the end B is such that when the handle (1 of the cam is elevated the end B, together with the cheekpieces, cam, and shoes, may be slid freely outwardly and inwardly along the ridge-pole section B and when the desired adjustment is reached the end piece may be locked firmly to the ridge-pole by simply depressing the handle d, thereby rocking the cam D in a direction to depress the shoes E E into firm gripping contact with the ridge-pole section B, pinching it firmly between the upper face of the section B and the shoes. To further steady the end sections in their adjustments, I provide guide-pieces F F, arranged to embrace the opposite sides of the part b of the end piece and a portion of the under side of said part, the said pieces F B, being secured to the opposite sides of the ridge-pole section B by a bolt or rivet f. The explanation of the means for clamping the end B in the de sired adjustment with respect to the ridgepole section B applies equally well to the means for clamping the end B in the desired adjustment with respect to the said ridge-pole section.

Toprovid'e for sustaining the awning in an extended adjustment, I provide arms G G, hinged one at each end of the ridge-pole section 13 and arranged to fold over into the position (shown in Fig. 1) when the ridge-pole is in its contracted position and out int-o the position'(shown in Fig. 2) when in its extended adjustment. The ends of the arms G G are conveniently provided with socket-pieces The adjustment of the shoes E 1 g g for slipping over the ends of the arms and holding the end Spreaders H H of the awning.

It will be observed that the extension of the ends may be any desired extent Within the limits of their length from the contracted position (shown in Fig. 1) to the extended posivtion, (shown in Fig. 2,) and that'the parts may ing-legs and a backbone formed in sections,

one of said sections being formed of spaced bars, of a clamp provided with a cam forlocking the sections together and a guide partially embracing one of the bars of the spacedbar section and connected with the adjacent section for holding the parts in the desired relation to one another, substantially as set forth.

2. The combination with the extensible backbone, of a folding awning-support hinged to the backbone and arranged to swing from its extended adjustment over into a folded position alongside the backbone, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two witnesses.

ISAAC E. PALMER.
